If that doesn't work (let us know if it does!), you can always fall back on OSM. Its buildings have been getting better, to the point where they're often acceptable for scales of 1:20,000 and smaller. No 3D though. (Maybe wait a few years for that!)

I was under the impression that commercial licensing is not available for Google Warehouse data? I will most likely be purchasing a dataset which includes 2D footprints from DMTI. (http://www.dmtispati...treetfiles.aspx) It's a fairly cost effective solution, but unfortunately their footprint data is approx 1.5 years old.

It's hard to imagine footprint data that's more recent than 1.5 years. Certainly not Google's. I work with buildings in Ottawa and Toronto all the time, and not only are Google's at least that old, their selection and depiction are also questionable. In any case, you'll have lots of revising and editing to do -- depending on the purpose / scale of the map, of course.

http://www.arcgis.com has Toronto data showing building footprints. It comes originally from the City of Toronto but they don't show it on their mapping site. You might be able to purchase data from them but it may be a little expensive.
